Ahead of the 2015 Welcome to Jamrock Reggae Cruise, which is now into its second consecutive round trip between Miami (United States) and Jamaica, the quartet TOK had well-publicised unity issues. Still, they made the trip on the Norwegian Pearl and ended up being the final main-stage performers as heavy rain cut short the open-air concert on the ship's Tahitian Pool Deck. On Friday night, Mykal Rose, with Sly and Robbie, Julian 'Juju Royal' Marley, and Capleton were scheduled to perform after TOK. As the performances were shifted indoors to the Atrium on level seven, Capleton was the only one of the three who got to perform on the sound system, Kurt Riley central to keeping the party going for a full house as the party people filled the space. Black Scorpio also had a turn at the control tower.

In some ways, it was an obvious gathering of nations as reggae cruisers were encouraged to represent their countries by wearing outfits of their national colours. Many did, clutching flags to enhance the effect. Bermuda, Trinidad and Tobago, and the United States were especially represented in the crowd. Earlier in the day, Shinehead had said there were 45 nations represented on-board the Norwegian Pearl, the diversity evident in the flags mounted around the Tahitian Pool Deck.

In a high-energy performance, coordinating movement as well as voice, TOK addressed the matter of their long-term cohesion, one member talking about rumours that the group was breaking up. He asked the audience members if they wanted to see TOK disband, and there was a strong negative response.

So, the TOK member explained, sometimes people get to a stage "where a man want to be his own boss", but there is still mutual support. Supporting the explanation was Solid as a Rock.

Before their performance was cut short by the rain, TOK had sent the ladies to the lead and encouraged all to get "mad in here". They revisited earlier times with Eagles Cry, honoured Eric Donaldson with Land of My Birth, and were into No Man when the rain came down in earnest.
